Abstract: Disclosed are a range hood and a vehicle. The range hood includes a box, a fan, and a first baffle ring. The box is provided with an accommodation cavity, and an air inlet and an air outlet communicating with the accommodation cavity. The fan is at least partially housed in the accommodation cavity, and includes an impeller and a motor which is connected to and configured to drive the impeller. In the axial direction of the impeller, projection of the impeller is within projection of the air inlet. There is a gap between the projection of the impeller and the projection of the air inlet. A projection of the first baffle ring covers the gap in the axial direction of the impeller.

Abstract: A range hood is provided. The range hood includes a volute casing, a volute casing air inlet and a volute casing exhaust outlet in communication with a hood exhaust outlet are provided in the volute casing. The volute casing includes a fixed housing part and a movable housing part, the movable housing part is movable relative to the fixed housing part; the fixed housing part is fitted with the movable housing part and air is discharged from the volute casing exhaust outlet when the movable housing part is in a closed position; the movable housing part is staggered relative to the fixed housing part to allow the air to be discharged into a room when the movable housing part is in an open position. When the range hood exhausts air to the room, a flow distance of the air is short, improving operational efficiency.

Abstract: A range hood includes a housing defining a first outer air vent and a second outer air vent; a volute casing disposed within the housing, including a volute casing body having a bottom plate, a top plate and a side encasing plate disposed between the bottom plate and the top plate, the volute casing body defining an outer air outlet communicated with the first outer air vent and the second outer air vent, an opening direction of the outer air outlet being orthogonal to that of the second outer air vent; a fan wheel disposed within the volute casing body; and an outer switching cover plate movable between a first position, in which the first outer air vent is opened and the second outer air vent is closed, and a second position, in which the first outer air vent is closed and the second outer air vent is opened.
